I went to gym for gaining muscle in 2011 and my progress was very slow, after couple of months continuing gym, I left it.

For last six months my lower belly is getting big. And I am feeling weak now a days.

I want to gain some weight with mass and want to loose my belly fat(its look really odd).

I have read couple of fitness blogs they suggest to go to gym and do weight training. But now its not possible for me to go to a gym(nearest gym is far away from home and I dont have much time to go there).

What I can do, I can buy light(cheap) instruments and also can arrange better food. And I can do some home exercise.

Do you guys have any specific suggestions? How can I recover from this situation?

I dont need six pack, what I want to achieve like a better shape with some mass and strength.Btw I live a hacker's life style(lots of coca cola, beers and chocolates, pizzas)
